Private CI/CD using Docker, Deis, and Drone

Created by Paul Czarkowski / @pczarkowski

Deis

Platform as a Service
Think private Heroku
CoreOS + Docker
12 factor

Deis Architecture

3+ CoreOS Servers
etcd / fleet
`deisctl` for operations
`deis` for users

Installing Deis

Excellent tooling/documentation for installing.

Installs on AWS as easily as:




$ ./provision-ec2-cluster.sh
{
    "StackId": "arn:aws:cloudformation:us-west-1:413516094235:stack/deis/9699ec20-c257-11e3-99eb-50fa01cd4496"
}
Your Deis cluster has successfully deployed.
Please wait for all instances to come up as "running" before continuing.
$ export DEISCTL_TUNNEL="deis-1.example.com"
$ deisctl install platform

Deis installed.
Please run `deisctl start platform` to boot up Deis.

Using Deis


$ git clone https://github.com/paulczar/example-python-flask.git
$ cd example-python-flask
$ deis create
$ git push deis master

POWERED By Deis

Drone

Automated Tests / Builds.
Very similar to TravisCI.
Available as both SaaS and OpenSource.
Tests/Builds run in Docker containers.
Installable from a .deb on Ubuntu.
Oauth integration - github, gitlab, bitbucket
Poor performance unless AUFS.

.drone.yml

Very similar to .travis.yml
